Description
The Bently Nevada 133396-01 is an Overspeed Detection I/O Module designed for use in the 3500 Series Machinery Detection System. It serves as a rear I/O interface for the 3500/53 Electronic Overspeed Detection System, providing critical signal routing, power supply conditioning, and interface connections for tachometer protection applications.
The 133396-01 module interfaces with proximity probes or passive magnetic pickups to supply a -24 Vdc power source to transducers and routes proportional +4 to +20 mA recorder output values corresponding to system full-scale speed (rpm). It is epoxy-sealed for environmental protection and operates within 3500 racks configured with redundant power supplies to meet API 670 and API 612 standard requirements for highly reliable machinery overspeed protection.
Features
Epoxy-Sealed Construction: Designed with epoxy sealing to protect internal circuitry from environmental exposure.
Integrated Transducer Power Supply: Delivers -24 Vdc power directly to connected proximity transducers or sensors.
Proportional Recorder Output: Provides a +4 to +20 mA current output proportional to the module's full-scale speed range.
Short-Circuit Immunity: Operation remains unaffected by potential short circuits on the recorder output line.
Redundant System Integration: Designed for full integration with 3500/53 monitor modules in 2-out-of-2 or 2-out-of-3 voting architectures.
Applications
API 670 and API 612 compliant machinery overspeed protection systems
Steam turbine, gas turbine, and industrial rotating equipment monitoring
3500 Series Machinery Detection System installations requiring rear I/O signal interfaces
